Comfort Deluxe Self-Inflating Sleeping Mat

Better than your bed

Sleeping Bag Temperature Ratings Explained

The EN Rating scale is a scientific test to determine the warmth of a sleeping bag. The test produces a Lower rating (for male sleepers) and a Comfort rating (for female sleepers). Both are listed in the features table on the product page.

A unisex sleeping bag with a Lower limit of 23ºF means a man should be comfortable down to air temperatures of 23ºF. The same bag will also have a Comfort limit, in the realm of 32°F, so a woman would be comfortable down to an air temperature of 32ºF. These ratings require a sleeping mat with an R-Value appropriate for expected ground temperatures – without this, the sleeping bag itself is unlikely to keep the sleeper warm enough.

A variety of factors impact sleeping bag warmth - the above temperatures are merely guidelines, not guarantees. It’s important to think of a sleeping bag, an appropriately insulating sleeping pad and a liner as a sleep system. For example - if you plan on sleeping in nighttime air temperatures of 27ºF / -3°C, choose a bag with a gender-appropriate rating of 23°F / -5°C, plus a sleeping mat with an R-Value of 2.5 to 3, and consider a Reactor thermal liner.

The ultimate in luxury for base campers, van-dwellers, and overlanders, the Comfort Deluxe Self-Inflating Sleeping Mat features four inches of plush foam and a 30D stretch knit fabric on the upper surface for a luxurious warm feeling when it’s cool and cool feeling when it’s hot. The flip-over multi-function valve makes packing up the mat relatively easy – it prevents air from being drawn back into the mat as you roll it up.

Be aware - if you pull out a Comfort Deluxe for house guests, they may end up staying longer than originally planned…

Our blog post "Which Mat Should I Choose" has some helpful tips on picking the perfect mat – frankly, there are very few alternatives to a Comfort Deluxe Self-Inflating Mat for the vehicle-based camper.

Is the Comfort Deluxe Self-Inflating Sleeping Mat...?

Insulated well enough for three-season temperatures? Absolutely. The Comfort Deluxe Self-Inflating Mat has a tested R-Value of 6.5 – suitable for even really cold outside temperatures.

Easy to pack up? Relatively easy. The flip-over valve prevents the mat from drawing air back in while it is being rolled up – but a mat of this size – especially the Double - still requires some effort to pack into its stuff sack.

Small enough when packed to use for non-motorized travel? No. The packed volume is similar to a folding camp chair, so the Comfort Deluxe Self-Inflating Mat is really not suitable for human-powered travel.

Technical Features

Delta Core™

The innovative Delta Core™ system maximizes the comfort and thickness of our Self Inflating mattresses while minimizing weight and bulk. 40% of the initial volume of the PU foam is removed in horizontal Delta-shaped cores, giving minimal weight and packed size. Importantly, the top and bottom surface of the PU foam remain completely intact. This ensures consistent warmth along the full length of the mattress and significantly improves bonding of the foam to the shell fabric, which reduces the chance of delamination.

The shape and size of the Delta Cores™ are adjusted across the different thicknesses of our mattresses to ensure strength and durability combined with excellent support. The horizontal Delta Core™ technique is used in our Comfort Light SI, Comfort Plus SI, and Comfort Deluxe SI models.

SI Multi-Function Valve

We have literally put a new twist on our very successful multi-function valve so it specifically addresses the inherent characteristic of self-inflating mats - that is, the problem of the foam trying to re-inflate as you're packing up. We've engineered the "one-way" inflation valve to be reversed and used to prevent the mat from drawing air back in. This allows you to roll the mat up as small as possible without fighting re-inflation as you go. This patent-pending valve design has the same slim profile, faster inflation than traditional screw valves, easy pressure fine tuning, and super fast deflation rate as our air mattresses and pillows.

Pillow Lock™ System

The Pillow Lock™ System comprises of self-adhesive hook-and-loop patches which are supplied with all Sea to Summit sleeping mats (as of Spring 2019),

Attached to your sleeping mat, these patches secure your pillow and prevent it slipping – yet they will not snag on clothing or other lightweight fabrics.

All Sea to Summit Pillows (as of Spring 2019) are compatible with this system. Existing pillows can be made Pillow Lock™ compatible by adding an Aeros Pillow Case.

Review by Laura H. on 27 May 2020review stating Great pad for car/RV camping

I bought this pad with the intention of using it while tent camping and as a topper for our RV mattress. Super plush and comfortable. Comes with its own carrying bag, does not roll up small but that was not an issue for me at all. Wanted something that was comfortable and thick. This checks all the boxes!

Super comfy! Big so I

Review by Ella N. on 18 May 2020review stating Super comfy! Big so I

Super comfy! Big so I wouldn't want to carry it but it's great for car camping or on a river trip when you don't have to carry your own gear. Wish the self-inflating aspect was a little more self-inflating....maybe it will get better with time??

5, but I plan to spend a lot more this summer!

Coldest Temperature Used:

Near freezing but it's very well insulated so I'm sure it would be a good fit for winter camping.

Perfect for car/base camping

Review by Kase C. on 14 May 2020review stating Perfect for car/base camping

I'm Search and Rescue. There are a lot of nights where I have to sleep in my truck at base camp or just catch some shut eye before I drive home. It really wide and plenty thick for a soft or supportive sleep. I can toss and turn all night and not wake up sore.

Q: I currently own the Comfort Deluxe Self Inflating mat and I love it. I am going to be using it on my next trip which will be 8 months long. Are there any custom fit sheets or something for this mat? That way I can use it as a normal mattress on top of my cot and have the ability to clean it periodically.

A: G’Day – thanks for your question! Glad to know the Comfort Deluxe SI Mat is working so well for you. Sorry to say we don’t have fitted sheets for the Comfort Deluxe range – but it sounds like an excellent suggestion which we will pass on to our Design team. In the meantime, the rectangular shape/vertical sides of the mat would make this a fairly straightforward home-sewing project…
